A little personal project/test to try 3D printing some components. Really enjoyed making this design and can't wait to start building this week!

feedback always appreciated.

See i took a f450 frame kk1.2.5 fc and fsi6 transmitter and reciever. Say me i built everything. For detection I took ultrasonic sensors and Arduino nano . How can I attach ultrasonic sensors and Arduino nano to thta drone just for obstacle detection . Please say me as soon as possible 25th July is the submission day ..

Hey, so i recently acquired a astrorc carbonfly25 pusher frame for my first build and was wondering what I could all do to push the endurance of it to get a bit more flight time. Currently I want to use it for low light operations and scouting for airsoft/milsim events where the fields aren't too big but there's a ton of trees and forest.

It's going to be my first actual build that isn't just plug and play. Any ideas help.

Anyone tried DIYFPV Builder? Any success?

It seems like a great idea, but it doesn’t seem to be fully functional.
Cant create a project, cant add/create a new part, none of the parts for my last build are in the catalogue. Blocked at all avenues, and I’m very willing spend time to add parts to expand it’s capabilities.
It has the potential to be a great tool.

Hey all,

first time FPV build here. I recently started putting together my first drone. I am using a DJI o4 air unit pro and a kiss flight ultra v3. I think I have realized I can not use the pin to pin connectors because on the FC its only up to 5V. Do I need to unpin the wires on the FC side and solder them on to the pads instead like the 12V. Sorry I am new to all this and just a bit confused but any feedback would be appreciated.

Hello! I'm doing a little engineering project and I'm very stuck.

So, I've soldered all of my motor phase wires to my zeus 48A ESC (and all of it should be connected and working- i've checked continuity with my multimeter), I made a special connector thing that takes the 4 signal wires and one ground wire and plugs it into the pixhawk's M and - port. I'm using missionplanner, and am trying to test the motors, but they won't spin.

also, every time I turn the power on, the ESC does it's startup chime, so It's getting power. I just don't know why the motors aren't spinning. Any suggestions?

Hi,

If I wanted to build a camera platform drone, where I wanted stability and smooth flight, ( probably using a DJI O4 VTX ) and I wanted to avoid goggles, what display options would I have? Is there something like the DJI N2 remote controller, or would I have to have a separate video receiver and display device?

I was tempted to buy an off the shelf solution, but as an engineer, who can write code and solder (!) I'm drawn to self build. I COULD just go and buy a Lito X1 and an RC N2, but that would be the easy way...

Thoughts welcome!

Thought I’d share my recently built 2.5 inch drone. Frame is custom designed by me and printed in PET-CF filament, making it surprisingly stiff. AUW 198g, could’ve saved some weight and space using an AIO board but I made do with what I already had. I’m very happy with it!

Hi everyone

So I have gotten into FPV flying during the past few months, but I have mostly done simulator (I have around 80h on Uncrashed). I recently bought the BetaFPV's Aquila 16 Kit, which is fun and imho a good way to get started, but it is also quite limited.
I would like to try assembling a drone for myself, but as I don't know anything about it, I was wondering if someone had a good compo to recommand ? I do not wish to start with something that would exceed 2-300€, and would also allow me to keep my goggles (VR03 FPV Goggles – BETAFPV) and controller (LiteRadio 2 SE Radio Transmitter – BETAFPV).

If anyone has any tips to share, it will be greatly appreciated !

Thanks everyone and have a gerat day :)

Hi!

New to FPV and this effort is a 2 year in the making project.
Life gets in the way and has drawn this out. I've finally gotten to getting things put together and I'm seem to be struggling with firmware/motor config options?

I could really use some insight.

My current issue is that in betaflight, I am able to get the motors to "twitch" and now they are all beeping when i move the sliders. I recently solved a soldering issue where one wire wasn't good and resulted in no beeping. Fixing that, I thought might solve the "twitching" but no dice.

The spin of the props seems choppy/twitchy.

Any insight into this issue would be appreciated. My build is powered by a single 18650 wired into my AIO.

• Frame: 3D Printed Micro Long Range Frame (Thingiverse)
• Flight Controller / AIO: HGLRC Specter 10A 1-2S ELRS AIO VTX 400mW F411
• ESC Firmware: Bluejay (Z-H-30, 48kHz)
• Flight Controller Firmware: Betaflight 4.5.3
• Motors: 4× Happymodel EX1202.5 11500KV Brushless Motors
• Camera: Caddx Ant Nano
• Receiver: Integrated SPI ExpressLRS (ELRS)
• Video Transmitter (VTX): Integrated 5.8GHz 400mW VTX
• Antenna: HGLRC Hammer Mini 5.8GHz RHCP 2.5dBi
• Radio Controller: Radiomaster TX12
• Battery: 1S 18650 Li-Ion Cell

can provide pictures and answer follow up questions. feel free to dm too.

I'm trying to DIY a new drone and try to calculate the release velocity, but I got confused:

A rail-based pneumatic launch system has an elevation angle of 30 degrees, a total rail length of 20 ft, and an acceleration stroke length of 15 ft. The UA weighing 100 lb is installed at 5 ft above ground level and must clear a 50 ft obstacle and attain a launch velocity of 60 kts to begin climb out once it has cleared the obstacle.

What is the release velocity?

I’m looking for Chinese websites to buy parts for my project, which is about cleaning high‑voltage transmission lines. Any suggestions for this project would also be helpful.
